Welcome to TSF!!
Hi,
I would like to help you but our
Rules state that I can't as this is a school project. Please take a look at them.
The only thing that I can tell you without getting in trouble is that you need to look at what a LAN is, and break it down from there.
EDUCATIONAL ASSISTANCE
While we are happy to promote the education of users, we feel it is inappropriate to circumvent the learning process by directly assisting with assignments and projects of an educational nature. Direct answers to school or college assignments are not allowed and will not be given. However, if a user is having trouble comprehending a certain topic, the members and staff at TSF will be happy to provide assistance with understanding the topic.
Sorry
Cheers!
